Treatment of textiles and agents therefor



Patented Aug. 22, 1933 UNITED STATES PATENT: OFFl TREATMENT or TnxTmasnNnnenNTs,

Heinrich Ulrich and Joseph Nuessleln, Ludwigshafen-on-the-Rhlne, Germany, or: to I. 'G. Farbemndustrie Aktiengesellschaft, Frankl'ort-on-the-Main, Germany No Drawing. Application March 16, 1931, Serial No. 523,180, and in Germany March 20, 1930 11 Claims.

o1'n5inx-N CHrCHa 16 e e in which x is hydrogen or an alkyl, aryl or cyclealkyl radicle which may also contain a substituent, as for example a hydroxyl or amino group and in which morpholines one or more hydrogen atoms of the nucleus may be substituted for example by alkyl groups. Ethers of the aforesaid nature are for example N-methyl, 2.6-dimethyl or N-hydroxyethyl morpholines, N-phenyl morpholine, 'N-cyclohexyl morpholine and the like. The said ethers may be employed as such or in the neutralized form i. e. in the form of their salts with inorganic or organic acids, such as hydrochloric, sulphuric, formic or acetic acids or the acids of the animal or vegetable fats or oils and the like. The amount of the ethers used will usually vary between 0.1 and 5 per cent, and preferably between 0.2 and 0.5 per cent, by weight of the bath.

The said ethers as well as their salts are usually readily soluble in water and have in particular the property of promoting the wettingand'penetration of textiles by baths of liquids. They also have a good solvent power for many organic sub- 40 stances, such .as fats, oils, dyestuifs and the like,

and they may therefore be employed with advantage for washing and stripping purposes. For the said purposes, the bases or their salts, as for example their salts with acidsof vegetable or animal oils or fats or their synthetic equivalents, are suitable alone or in combination with, for example equal amounts of, dispersing agents, such as soaps, products similar to Turkey red oil, condensation products from amines, or hydroxy-alkyl amines, with fatty acids, such as oleic or stearic acid or sulphonic acids, such as sulphonated palmitic acid, as for example amides, esters or ester-amides, or non-fatty dispersing agents, such as alkylated aromatic sulphonic acids or their salts or with organic solvents, such for scouring100 kilograms of wool waste containas benzine or carbon tetrachloride, or with several of these substances. For the sake of brevity, the water and the other substances improving the textiles or assisting the improvement will be referred to in the appended claims as agents capable 50 of improving textiles.

The following examples will further illustrate the nature of this invention, but the invention is not restricted to these examples.

Example 1 05 500 grams of N-hydroxyethyl morpholine,

OHr-CH! bm-cm obtained by splitting oil? water from tri-ethanolamine by means of 10 per cent sulphuric acid at 170 0., are added to 1 cubic metre of a bucking bath containing per liter 3 grams of caustic soda and 2 grams of soda for each 100 kilograms of cotton material. v The high solvent power for cotton wax and the high penetrating power of the hydroxy ethyl morpholine assists the bucking process in an excellent manner so that the usual time for boiling may be reduced by about one third to a half. a

Example 2 CH: CHa-EH obtainable by splitting off water from di-isopropanol amine by heating for 3 hours to 1'70 C. in

the presence of a '70 per cent aqueous sulphuric acid, are added to each liter of water necessary ing oil and fat, the temperature of the bath being 40 C. and the material is worked for half an hour, squeezed out and rinsed. An excellent cleansing of the material is obtained. Instead of the said morpholine, the product obtainable therefrom by neutralization with fatty acids, for example 5 grams of the salt with oleic acid, or withpalmitic sulphonic acid and which has a very high wetting, emulsifying and washing power may be employed.

Example 3 4 kilograms of 80 per cent formic acid and 2 kilograms of the cyclic ether. 5 7 OKs- H:

= oiHu-n o onr-om obtained by splitting oil. water from cyclohexyl di-ethanol amine, and which has preferably been neutralized with oleic acid or with sulphonation products of aliphatic compounds containing at least 8 carbon atoms, such as oleic sulphonic acid, stearic sulphonic acid, Turkey red oil acid or the acid sulphuric ester of cetyl alcohol, are added to the quantity of hot water necessary for stripping (temperature 60 to 70 C.) 100 kilograms of artificial wool waste, the goods are introduced into the bath, 3 kilograms of zinc formaldehydesulphoxylate are added, the bath heated to boiling, boiled for minutes and the goods rinsed.

By reason of the good solvent power of the ether.

employed for dyestufis and their decomposition products, an excellent stripping efl'ect is'obtained.
